Abstract

Background and Purpose—Cerebral white matter lesions (WMLs), a surrogate for cerebral small-vessel disease, have been shown to be associated with decreasing mobility, gait instability, and falls. The aim of this study was to investigate whether WMLs of the brain are associated with increased incidence of hospital admissions because of any trauma and hip-fractures in a cohort of patients with stroke.

Methods—We included 383 consecutive patients aged 55 to 85 years with ischemic stroke admitted to the Helsinki University Central Hospital (The Stroke Aging Memory cohort) with a 12-year follow-up. National register data were reviewed for hip-fractures, other traumatic injuries, survival data, and causes of death. WMLs were rated using MRI and dichotomized as none to mild and moderate to severe. The data were analyzed using Kaplan–Meier plots (log-rank) and a complex Cox multivariable hazards models for multiple cases per subject to assess hazard ratios with their 95% confidence intervals.
